Tuberculosis keeps its importance as a very serious public health problem throughout the world and in our country. Extrapulmonary placed tuberculosis cases create a significant clinical problem with the cause of the difficulties faced in the distinctive diagnosis. In contrast, we aimed at discussing the case found in the mediastane thorax BT with lymphadenomegals in pathological dimensions, in the mediastinoscopic biopsy due to the high FDG retention in the lymphadenomegals in the PETBT with tuberculosis lymphadenitis. The 80-year-old lady patient was placed on the lung graph on the detection of extension in the right paratrakeal area. Toraks BT and MR images supported that this extension was compatible with the mediastinal tumor. In the PET-BT study, it was observed that the audience increased FDG holding in favor of malignity. However, the result of mediastinoscopic biopsy was as tuberculosis lymphadenitis and tuberculosis treatment began. It should not be remembered that among the pathologies that cause mediastinal masses that are considered malignant even in adult patients, tuberculosis lymphadenitis may also be found and that tuberculosis lymphadenitis may show increased FDG retention in the PET-BT study.
